[0002] To meet user needs, coffee machines usually have the function of making milk froth. When making milk froth, the user usually needs to pour milk into a cup, and then extend the steam pipe of the coffee machine below the milk liquid surface. In this way, the user not only needs to hold the milk cup, but also easily gets burned when making milk froth. For this reason, many new coffee machines have made improvements in this regard. For example, as disclosed in the Chinese utility model patent "Milk Heating and Frothing Rod for Coffee Machine" with application number 202222599865.7 (authorization announcement number CN 218338206 U), a milk tank for holding milk is installed in the body of the coffee machine, so that the user does not need to hold the milk tank. However, this will increase the size of the coffee machine, and each time milk is added, the shell of the coffee machine needs to be opened and the milk tank needs to be taken out, which is relatively complicated. There is another improvement direction, as disclosed in the Chinese patent with patent number 201080053542.5 (authorization announcement number CN 120905585B), the coffee machine includes at least one first steam supply nozzle and a milk container that can be connected to the first steam supply nozzle. The milk container is detachable and can be installed outside the coffee machine when milk frothing is needed.
